A low-fire, low-dielectric ceramic composition is disclosed. The ceramic composition comprises a mixture of finely divided particles consisting of 30-90% by volume of Ca--Ba--Al--Zn--Si glass and 70-10% by volume of oxides, which can be densified up to 95% at temperatures of 800-1000.degree. C. The

A low-fire, low-dielectric ceramic composition is disclosed. The ceramic composition comprises a mixture of finely divided particles consisting of 30-90% by volume of Ca--Ba--Al--Zn--Si glass and 70-10% by volume of oxides, which can be densified up to 95% at temperatures of 800-1000.degree. C. The sintered body produced thereby exhibits a dielectric constant in the range of 6-10 and a dielectric loss in the range of 0.01%-0.5% at 1 MHz. The ceramic composition can be processed with organic solvent, polymeric binder and plasticizer to produce a green sheet which is co-firable with high electrical conductivity metal such as gold, silver, silver-palladium and copper.
